■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (→P. 507)
●If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this vehicle. Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts or parts not designed for this vehicle may be unusable.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions. Failure to do so may cause damage to the vehicle, and possibly a fire or injury. ●Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
●Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
●Do not modify the fuses or fuse boxes. ■Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring near the fuse box. Doing so may cause electric shock, resulting in death or serious injury.

■Replacing light bulbs
●Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights. The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion. If the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may result in heat damage, fire, or water entering the headlight unit. This may damage the headlights or cause condensation to build up on the lens.

5-1. Essential information If your vehicle needs to be towed
If towing is necessary, we recommend having your vehicle towed by your Toyota dealer or a commercial towing service, using a lift-type truck or flat bed truck. Use a safety chain system for all towing, and abide by all state/pro- vincial and local laws.
Before towing
The following may indicate a problem with your hybrid transmission. Contact your Toyota dealer before towing. ● The hybrid system is operating but the vehicle will not move. ● The vehicle makes an abnormal sound. If there is a malfunction in the P position control system, the smart key system or the immobilizer system, or if the 12-volt battery is dis- charged, the vehicle cannot be towed with the front wheels on the ground, as the front wheels may be locked. In this case, transport the vehicle with both front wheels or all four wheels lifted.

5-1. Essential information
Emergency towing
If a tow truck is not available in an emergency, your vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet(s). This should only be attempted on hard surfaced roads for short distances at under 18 mph (30 km/h). A driver must be in the vehicle to steer and operate the brakes. The vehicle’s wheels, drive train, axles, steering and brakes must be in good condition.

CAUTION
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on the emergency towing eyelets and the cables or chains. Always be cautious of the surroundings and other vehicles while towing.
●Do not turn the “POWER” switch off.
This may lead to an accident as the front wheels will be locked by the parking lock.
●If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely. If not securely installed, towing eyelets may come loose during towing. This may lead to accidents that cause serious injury or even death.

5-2. Steps to take in an emergency
*1: Open door warning buzzer:
The open door warning buzzer sounds to alert one or more of the doors is not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).
*2: Seat belt warning buzzer:
The driver’s and front passenger’s seat belts reminder sounds to alert the driver and front passenger that his or her seat belt is not fastened. The buzzer sounds intermittently for 10 seconds after the vehicle has reached a speed of at least 12 mph (20 km/h). Then, if the seat belt is still unfastened, the buzzer will sound in a different tone for 20 more seconds.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact sensors, side impact sensors (front), side impact sensors (rear), driver’s seat position sensor, driver’s seat belt buckle switch, front passenger occupant classification system (ECU and sensors), “AIR BAG ON” indicator light, “AIR BAG OFF” indicator light, front passenger’s seat belt buckle switch, seat belt pretensioner assemblies, airbags, interconnecting wiring and power sources. (→P. 184)
■Front passenger occupant classification system (ECU and sensors),
seat belt reminder and warning buzzer ●If luggage is placed on the front passenger seat, the front passenger occupant classification system (ECU and sensors) may cause the warn- ing light to flash and the warning buzzer to sound even if a passenger is not sitting in the seat.
●If a cushion is placed on the seat, the front passenger occupant classifi- cation system (ECU and sensors) may not detect a passenger, and the warning light may not operate properly.

■If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If tires not equipped with tire pressure warning valves and transmit-
ters are used
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi- tions: (When the condition becomes normal, the system will work properly.) ●If electronic devices or facilities using similar radio wave frequencies
are nearby
●If a radio set at a similar frequency is in use in the vehicle ●If a window tint that affects the radio wave signals is installed ●If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings
●If non-genuine Toyota wheels are used (Even if you use Toyota wheels, the tire pressure warning system may not work properly with some types of tires.) ●If tire chains are used
